dsh-collapsible-models

With several model providers configured, the composer model picker turns into a scroll marathon. dsh-collapsible-models does exactly one thing well: it adds a collapsible triangle to every provider row in the dropdown, so you can fold or unfold each group with a single click and turn a flat wall of models into a tidy two-level list.

Under the hood the plugin registers a shadow entry at priority -1 over the stock picker while leaving the data layer completely untouched. Model catalog, current selection, reasoning-effort handling, loading states, and toast notifications all behave exactly as they do in the native UI. Collapse state lives only for the duration of the open dropdown and is never persisted. Group headers remain real, focusable elements, so keyboard navigation with Tab and Enter works unchanged, and aria-expanded plus accessible labels follow the active locale in both Chinese and English.

This is for anyone who has wired up multiple providers — OpenAI, Anthropic, a local Ollama instance, and friends — and ends up scrolling past dozens of models just to find the one they need. Install it, restart the harness once, and the picker becomes a clean provider-first, model-second flow without touching any existing configuration.
